Dr. Ranjith Ramanathan is an associate professor in our department. He currently teaches both undergraduate and graduate level courses, including the fundamentals of food science, food chemistry I, food chemistry II, analysis of food products, and advanced meat science.


Dr. Ramanathan's long-term research goal is to better understand the role of postmortem meat biochemistry to increase both the body of knowledge and economic benefits associated with improvements in muscle food appearance, particularly beef color. His research focuses on both fundamental and applied aspects of beef quality to better understand beef color issues. His research interests include:

  • Application of metabolomics to better understand meat quality changes
  • Understanding the mechanism of failure to bloom in dark-cutting beef
  • Myoglobin chemistry to understand metmyoglobin reducing activity and bloom
  • Cooked color defect
  • Role of mitochondria in beef color
  • Myoglobin and lipid oxidation
  • Antioxidants on mitochondrial function
